Question

this https://projecteuler.net/problem=641 is the problem I am trying to solve and below is my half solution.

void dice(int n) 
{
    int i, j, dices[n];

    for(i = 0; i < n; i++) {
        dices[i] = 1;
    }

    for(i = 1; i < n; i++) 
    {
        for(j = 0; j < n; j+=i)
        {
             dices[j]= dices[j] > 5?1:dices[j]+1;
        }
    };


    for(i = 0; i < n; i++) {
        cout << i+1 <<  "th dice is :" << dices[i] << endl;
    }
};

this is the part I do not get: Let f(n) be the number of dice that are showing a 1 when the process finishes . You are given f(100)=2 and f(10^8)=69. Find f(10^36).

from "f(100)=2" I understand that the 100th die should be 2 but f(10^8)=69 loses me.

Answer 1

Read the problem description again. There is a definition of f() there:

Let f(n) be the number of dice that are showing a 1 when the process finishes.

If is not a value of any specific die. Instead, the value of f(n) tells you how many dice in the n –dice row show 1 after completion of all turns.
